Find how much each earns

pres =6 and 3/4 times mec pay=17.25 times 6.75=116.4375, about $116.44
janitor is 3/4 or 0.75 of janitor=17.25 times 0.75=12.9375, about $12.94

add them

$17.25+$116.4275+$12.9375=146.615
round
$146.62

$146.625

<h3>Further explanation</h3>

<u>Given:</u>

  • At a factory, a mechanic earns $17.25 an hour.
  • The president of the company earns 6³/₄ times as much for each hour he works.
  • The janitor at the same company earns ³/₄ as much as the mechanic.

<u>Question:</u>

How much does the company pay for all three people employees' wages for one hour of work?

<u>The Process:</u>

Let us prepare a model for a mechanic earns $17.25 an hour.

\boxed{\$ 17.25}

Let us do multiplication on a fraction at first.

\boxed{ \ = \frac{3}{4} \times 17.25 \ }

\boxed{ \ = 3 \times \frac{1}{4} \times 17.25 \ }

\boxed{ \ = 3 \times \frac{17.25}{4} \ }

\boxed{ \ = 3 \times 4.3125 \ }

\boxed{\boxed{ \ 12.9375 \ }}

Then we make a model for the president of the company who earn 6³/₄ (six and three quarter) times as much for each hour the mechanic works. Recall that \boxed{6\frac{3}{4} \ parts = 6 \ parts + \frac{3}{4} \ parts}

\boxed{\$ 17.25}\boxed{\$ 17.25}\boxed{\$ 17.25}\boxed{\$ 17.25}\boxed{\$ 17.25}\boxed{\$ 17.25}\boxed{12.9375}

Let's calculate how much the president of the company earns for each hour.

\boxed{ \ = (6 \times \$ 17.25) + \$ 12.9375 \ }

\boxed{ \ = \$ 103.5 + \$ 12.9375 \ }

\boxed{ \ \$ 116.4375 \ }

And we also calculate for the janitors who earn ³/₄ as much as the mechanic.

\boxed{ \ = \frac{3}{4} \times 17.25 = 12.9375 \ }

Finally, let's add up all earning to find out how much does the company pay for all three people employees' wages for one hour of work.

\boxed{ \ \$ 17.25 + \$ 116.4375 + \$ 12.9375 = \$ 146.625 }

A survey reported in Time magazine included the question ‘‘Do you favor a federal law requiring a 15 day waiting period to purch
galben [10]

Answer:

Step-by-step explanation:

Confidence interval for the difference in the two proportions is written as

Difference in sample proportions ± margin of error

Sample proportion, p= x/n

Where x = number of success

n = number of samples

For the men,

x = 318

n1 = 520

p1 = 318/520 = 0.61

For the women

x = 379

n2 = 460

p2 = 379/460 = 0.82

Margin of error = z√[p1(1 - p1)/n1 + p2(1 - p2)/n2]

To determine the z score, we subtract the confidence level from 100% to get α

α = 1 - 0.95 = 0.05

α/2 = 0.05/2 = 0.025

This is the area in each tail. Since we want the area in the middle, it becomes

1 - 0.025 = 0.975

The z score corresponding to the area on the z table is 1.96. Thus, confidence level of 95% is 1.96

Margin of error = 1.96 × √[0.61(1 - 0.61)/520 + 0.82(1 - 0.82)/460]

= 1.96 × √0.0004575 + 0.00032086957)

= 0.055

Confidence interval = 0.61 - 0.82 ± 0.055

= - 0.21 ± 0.055
